5. Table 3: objects of indeterminate status

This table contains all the objects the status of which cannot be determined by our software. The main reason for the difficulty to classify an object is that there are not enough TLEs available or that the status has recently changed (satellite newly launched or recently manoeuvred). Indeed, at least 5 TLEs with the same status are needed to determine the category in which the object falls. Some bad measurements can also cause the failure to classify an object correctly. The objects are ordered according to their COSPAR designation. The following information is available:

The longitude histories of most objects in this category are plotted in Figures
